Description

Equipment and communication circuit with multiplexing formula antenna
[ technical field ] A method for producing a semiconductor device
The present invention relates to the field of communications technologies, and in particular, to an apparatus and a communications circuit having a multiplexing antenna.
[ background of the invention ]
In the existing mobile terminal device, multiple communication modes may exist simultaneously, for example, a mobile phone with dual-card dual-standby communication mode generally needs to be configured with four antennas: a secondary card global system for Mobile Communication (GSM) antenna, a primary card CDMA antenna, a primary card B26 main antenna, and a primary card B26 diversity antenna. Most preferably, four antennas are provided in the handset, as shown in fig. 1. However, adding one more antenna means that the terminal device needs to occupy the space of one antenna, which results in an increase in the volume of the terminal device, and is unacceptable for some terminal devices requiring portability, thinness, and beauty. Moreover, in a new terminal device, especially a terminal device with a metal shell, it is extremely difficult to add a certain antenna space and design one more antenna.
In the prior art, one antenna is configured to be used by a system with two different communication modes in a time division multiplexing manner, so that an additional antenna, for example, the system shown in fig. 2, is not added. However, the GSM carrying voice traffic is generally prioritized over B26 carrying data traffic, and control of single pole double throw switch 1 (SPDT) needs to be handed over to the vice-card GSM. Thus, when GSM occupies the antenna for a long time (e.g., talking), the B26 master set will drop due to no antenna being used, which results in the interruption of the LTE service of the master card. In practice, when the secondary card GSM is talking, the primary card CDMA is normally on standby, and ANT2 is idle most of the time. Therefore, the antenna scheduling of the system is not flexible enough, which causes the waste of antenna resources and degrades the system performance.

The first communication system circuit 303 is a GSM communication system circuit, the second communication system circuit 304 is a Long Term Evolution (LTE) communication system circuit, and the third communication system circuit 305 is a CDMA communication system circuit.
In the present embodiment, the second communication system circuit 304 includes a B26 master sub-communication system circuit 304a and a B26 diversity sub-communication system circuit 304B.
Further, the first switching sub-circuit 308 and the third switching sub-circuit 310 are both single-pole double-throw switching circuits, and the second switching sub-circuit 309 is a double-pole double-throw switching circuit.
The first switching sub-circuit 308 includes a control terminal 308a, a first connection terminal 308b, and a second connection terminal 308 c; the second switching sub-circuit 309 comprises a first control terminal 309a, a second control terminal 309b, a first connection terminal 309c and a second connection terminal 309 d; the third switching sub-circuit 310 includes a control terminal 310a, a first connection terminal 310b, and a second connection terminal 310 c.
In this embodiment and other embodiments of the present invention, the control terminal is a common terminal of the single-pole double-throw switch, and the connection terminal is a signal terminal of the single-pole double-throw switch or the double-pole double-throw switch.
Specifically, the control terminal 308a of the first switching sub-circuit 308 is connected to the first antenna 306, the first connection terminal 308b is connected to the first communication system circuit 303, and the second connection terminal 308c is connected to the first control terminal 309a of the second switching sub-circuit.
The second control terminal 309b of the second switching sub-circuit 309 is connected to the first connection terminal 310b of the third switching sub-circuit 310, and both the first connection terminal 309c and the second connection terminal 309d are connected to the second communication system circuit 304. The first connection terminal 309c is connected to the B26 primary diversity sub-communication system circuit 304a, and the second connection terminal 309d is connected to the B26 diversity sub-communication system circuit 304B.
The control terminal 301a of the third switching sub-circuit 310 is connected to the second antenna 307, and the second connection terminal 310c is connected to the third communication system circuit 305.
The control circuit 301 is connected to the control terminals of the first switching sub-circuit 308, the second switching sub-circuit 309 and the third switching sub-circuit 310. In this embodiment, the control circuit 301 may be a Modem or a CPU, and in another embodiment, the control circuit 301 may be a Field-programmable gate Array (FPGA) circuit.
The operation principle of the apparatus 300 of the present embodiment will be explained below.
The control circuit 301 sets a logic control signal in advance, and sends the logic control signal to the first switching sub-circuit 308, the second switching sub-circuit 309 and the third switching sub-circuit 310 according to the current communication mode of the device 300, so as to control the connection between the first switching sub-circuit 308, the second switching sub-circuit 309 and the third switching sub-circuit 310 and the first communication system circuit 303, the second communication system circuit 304 and the third communication system circuit 305 through the corresponding general purpose input/output GPIO interfaces, so that the first antenna 306 or the second antenna 307 is allocated to the communication system circuit corresponding to the current communication mode of the device 300 for use.
Further, the control circuit 301 sets the priority level of the first communication system circuit 303, the second communication system circuit 304, and the third communication system circuit 305 using the first antenna or 306 the second antenna 307 in advance according to the communication protocol of the first communication system circuit 303, the second communication system circuit 304, and the third communication system circuit 305, thereby setting the corresponding logic control signal.
Typically, voice traffic is first and data traffic is second. Based on this allocation principle, the communication system circuitry in the device 300 is configured accordingly to: the first communication system circuit 303 is a GSM system, the second communication system circuit 304 is an LTE system, and the third communication system circuit 305 is a CDMA system. In order to guarantee voice quality, it is necessary to enable the GSM system and the CDMA system to preferentially use antennas. Therefore, the control circuit 301 sets the priority levels of the first communication system circuit 303, the second communication system circuit 304, and the third communication system circuit 305 using the first antenna 306 or the second antenna 307 in advance according to the communication protocols of the first communication system circuit 303, the second communication system circuit 304, and the third communication system circuit 305 as follows: the first communication system circuit 303 uses the first antenna 306 with higher priority than the second communication system circuit 304, and the third communication system circuit 305 uses the second antenna 307 with higher priority than the second communication system circuit 304, and the corresponding logic control signals are set as follows: when the first communication system circuit 303 (GSM system) operates, the control terminal 308a of the first switching sub-circuit 308 is connected to the first connection terminal 308 b; when the first communication system circuit 303 is idle, the control terminal 308a of the first switching sub-circuit 308 is connected to the second connection terminal 308c, the first control terminal 309a of the second switching sub-circuit 309 is connected to the first connection terminal 309c, and the second control terminal 309b of the second switching sub-circuit 309 is connected to the second connection terminal 309d, that is, connected in a through manner. When the third communication system circuit 305 (CDMA system) operates, the control terminal 310a of the third switching sub-circuit 310 is connected to the second connection terminal 310 c; when the third communication system circuit 305 is idle, the control terminal 310a of the third switching sub-circuit 310 is connected to the first connection terminal 310b, the second control terminal 309b of the second switching sub-circuit 309 is connected to the first connection terminal 309c, and the first control terminal 309a of the second switching sub-circuit 309 is connected to the second connection terminal 309d, i.e., cross-connected.
Therefore, the control circuit 301 outputs a logic control signal according to the currently operating communication system circuit of the device 300 to control the connection of the control terminals and the connection terminals of the three switching sub-circuits, so that the two antennas are allocated to the currently operating communication system circuit for use.
Thus, the antenna resources obtained by the second communication system circuit 304 (LTE system) are: when the first communication system circuit 302 and the third communication system circuit 305 are both idle, the first antenna 306 and the second antenna 307 are simultaneously obtained (at this time, the requirement that the B26 main set subsystem 304a and the B26 diversity subsystem 304B work simultaneously can be met); when one of the first communication system circuit 303 or the third communication system circuit 305 is idle, the second antenna 307 or the first antenna 306 is obtained accordingly (this time, the requirement of one of the B26 master set sub-communication system circuit 304a and the B26 diversity sub-communication system circuit 304B to operate can be satisfied); when both the first communication system circuit 302 and the third communication system circuit 305 are operating, no antenna is acquired (at this time, neither the B26 main set subsystem 304a nor the B26 diversity subsystem 304B is operating).
Referring to fig. 4, further, in order to enable the antenna resources obtained by the second communication system circuit 304 to be flexibly allocated between the two sub-communication system circuits, the second switching sub-circuit 309 allocates the antenna resources as follows: when the first communication system circuit 303 works to occupy the first antenna 306, the control circuit 301 controls the second control terminal 309b of the second switching sub-circuit 309 to be connected to the first connection terminal 309c, and the first control terminal 309a is connected to the second connection terminal 309 d. When the first communication system circuit 303 is idle, the control circuit 301 controls the first control terminal 309a of the second switching sub-circuit to be connected to the first connection terminal 309c, and the second control terminal 309b to be connected to the second connection terminal 309 d.
Therefore, the B26 master subsystem 304a of the second communication system circuit 304 obtains antenna resources to the maximum extent: when the first communication system circuit 303 (GSM system) and the third communication system circuit 305 (CDMA system) operate at different time intervals, the B26 master subsystem 304a always has allocable antenna resources; when the first communication system circuit 303 (GSM system) and the third communication system circuit 305 (CDMA system) operate simultaneously, the B26 master-set sub-communication system circuit 304a has no allocable antenna resources, and a signal "drop pit" inevitably occurs, and the "pit width" occupies the same time as the first communication system circuit 303 (the GSM system occupies a shorter antenna time than the CDMA system) occupies the first antenna 306, thereby minimizing system loss.
Referring to fig. 5, a circuit diagram of an apparatus having a multiplexing antenna according to a second embodiment of the present invention is different from the first embodiment in that the second switching sub-circuit 409 includes a first switch circuit 4091 and a second switch circuit 4092, and the first switch circuit 4091 and the second switch circuit 4092 are both single-pole double-throw switch circuits. The first switch circuit 4091 includes a common terminal 4091a, a first connection terminal 4091b and a second connection terminal 4091 c. The second switch circuit 4092 includes a common terminal 4092a, a first connection terminal 4092b and a second connection terminal 4092 c.
Specifically, the common terminal 408a of the first switching sub-circuit 408 is connected to the first antenna 406, the first connection terminal 408b is connected to the first communication system circuit 403, and the second connection terminal 408c is connected to the common terminal 4091a of the first switch circuit 4091.
The common terminal 401a of the third switching sub-circuit 410 is connected to the second antenna 407, the first connection terminal 410b is connected to the second connection terminal 4092c of the second switch circuit 4092, and the second connection terminal 410c is connected to the third communication system circuit 405.
